Answer:
Step-by-step explanation:
"Best estimate' doesn't happen automaticallly, because you have to define "best" in this context. We could merely round all numbers and work with the results:
For example, starting with the work inside parentheses, we have:
5 5/6 - (1 + 4) = 5 5/6 - 5. We must round 5 5/6 up to 6. Then the "best estimate' is 6 - 5, or just 1.

Answer:
A
Step-by-step explanation:
You know that the negative number with the largest magnitude is farthest to the left on the number line.
3/4 = 9/12
2/3 = 8/12
Then 3/4 > 2/3, so ...
-3/4 < -2/3
Answer:
$33.85
Step-by-step explanation:
Let X be the initial bill:
(100 + 20.7)% of X was paid
120.7/100 × X = 40.86
X = 40.86 × 100/120.7
X = 33.85252693
Answer: 27/36
Step-by-step explanation: It says there are 36 bikes (18 pairs), meaning that there are 2 bikes per pair because 18 multiplied by 2 is 36.
1 pair (2 bikes) are yellow.
3 pairs (6 bikes) are red.
For purple, add yellow and red together: 2 + 6 = 8. Subtract the total number of bikes from this: 36 - 8 = 28 purple bikes.
If you take out 1 purple bike, this leaves you with 27. The probability of choosing a purple bike out of the total (36), is 27/36.
